Over the weekend, Southwest Airlines shared an Instagram photo of dozens of medical professionals from Georgia, holding their hands in the shape of a heart, with smiles on their faces as they made their way to assist with the ongoing health crisis.

"While so many of us continue to feel the effects of the COVID-19 pandemic, no one knows what is happening quite like our medical professionals," the airline captioned the now-viral shot. "These brave souls soldier on in the midst of tremendous risk and exposure, constantly putting the needs of others above their own. Their selfless sacrifice is a beacon of light during such a dark time in our world, and no amount of gratitude and praise would ever be enough. Because of their courage, our family, our friends, our coworkers, our neighbors, and more have a fighting chance.

"More than a dozen healthcare professionals from Atlanta answered the call this past Friday evening to serve in New York," the caption continued. "This photo embodies it all: bravery, courage, and sacrifice. If it were easy, everyone would do it, but we know that is not the case. Thankfully, this group and countless others do it each day, and for that we are forever grateful and in their debt. So to all the first responders, medical professionals, healthcare workers, and anyone else on the front lines today and every day to keep us safe, thank you. #SouthwestHeart (📸 Southwest Employee Dayartra E.)."

The image has since been shared thousands of times across social media.
